Ok first off the beastlord ice nukes don't grey each other out. Most high end beastlords used to run 4 of them and chain them while meleeing. Due to their short casting time they add a substantial amount of dps. Of course this information is at least a year old. I would be willing to bet that if you parse the dps for a beastlord you will notice that chaining the nukes will give most beastlords a decent increase in dps.

Kinda pointless since page seems outdated but Beast DoT's for the most part are shitty because they cost a good amount of mana and get resisted a lot of the time. For the most part i ignore them and just save mana to chain nukes, works out much better.

Don't Lie you rangers want the bards so they can teach you how to do the perfect air harping with your bow! /Shrug Bard dps has more benefit to some classes I'd think that rangers would benefit more than others due to triple attack and flurry. However, none of that has been proven and proc rates conflict with each other you can only proc one spell in any given round of combat, with the exception of itemization weapon procs. So while it would be nice to do panther bard proc and your self buff proc in one round of combat. It will never happen.
